GENERAL DESCRIPTION
The Austin Semiconductor, Inc. AS8S128K32 is a 4 Megabit CMOS SRAM Module organized as 128Kx32-bits and user
configurable to 256Kx16 or 512Kx8. The AS8S128K32 achieves
high speed access, low power consumption and high reliability
by employing advanced CMOS memory technology.
The military temperature grade product is suited for military applications.
The AS8S128K32 is offered in a ceramic quad flatpack module per SMD-5962-95595 with a maximum height of 0.140 inches.
This module makes use of a low profile, mutlichip module design.
This device is also offered in a 1.075 inch square ceramic
pin grid array per SMD 5692-93187, which has a maximum height
of 0.195 inches. This package is also a low profile, multi-chip
module design reducing height requirements to a minimum.

ABSOLUTE MAXIMUM RATINGS*
This is a stress rating only and functional operation on the
device at these or any other conditions above those indicated
in the operational sections of this specification is not implied.
Exposure to absolute maximum rating conditions for extended
periods may affect reliability.
**Junction temperature depends upon package type, cycle time,
loading, ambient temperature and airflow. See the Application
Information section at the end of this datasheet for more information.
Voltage of Vcc Supply Relative to Vss.....................-1V to +7V
Storage Temperature..........................................-65°C to +150°C
Short Circuit Output Current(per I/O)...............................20mA
Voltage on Any Pin Relative to Vss..................-.5V to Vcc+1V
Maximum Junction Temperature**.................................+175°C
*Stresses greater than those listed under “Absolute Maximum Ratings” may cause permanent damage to the device.

NOTES
7. At any given temperature and voltage condition,
tHZCE, is less than tLZCE, and tHZWE is less than tLZWE.
8. ?W/E is HIGH for READ cycle.
9. Device is continuously selected. Chip enables and output
enable are held in their active state.
10. Address valid prior to or coincident with latest occurring
chip enable.
11. tRC= READ cycle time.
12. Chip enable (?C/E) and write enable (?W/E) can initiate and
terminate a WRITE cycle.
13. 32 bit operation
1. All voltages referenced to VSS (GND).
2. -3v for pulse width <20ns.
3. ICC is dependent on output loading and cycle rates.
The specified value applies with the outputs
1
open, and f=
HZ.
t
RC(MIN)
4. This parameter is sampled.
5. Test conditions as specified with output loading as
shown in Fig. 1 unless otherwise noted.
6. tHZCE, tHZOE and tHZWE are specified with CL= 5pF
as in Fig. 2. Transition is measured +/- 200 mV
typical from steady state coltage, allowing for actual
tester RC time constant.
